T-Birds still come with 22-18 gearing? if so I would replace the cranks and backwheel, or else you might have a struggle with BB learence when you swap for a t-pro, 221pr ect. My freind has the square tapeer echo cranks (the black ones, non CNC) and there really nice, feel preety stiff to and cheaper then most cranks at the moment. Use your old bb to (£52 from TB) As someone else said, T-Master wheels are preety good, It does the job and quite well, Sealed bearings, flip flop style hub and a bolt up axle. Built onto a ronnie, Its goign to be a strong wheel Could always have extra truing and tensioning from Adam too, for £5. So thats £60. Leaves you £278 for whatever frame you wanted But as someone said, the 221PR's look nice, and I bet they ride nice. A new BB and headset would'nt go a miss to if its the standard onza parts Just to let you know, shimano un52 BB, £11. FSA pig headset, £20. Tom
